Schematic:

In addition to this shield, you will need a Bluetooth adapter to experiment with Amarino. You can buy one of the following Bluetooth adapters:

a. BlueSMiRF- Mate Silver:
This module is cheaper than other BlueSMiRF versions available at Sparkfun. The shield works with other modules also, but you can stack ONLY Bluetooth Mate Silver on to this shield. OTHER VERSIONS OF BLUESMIRF DOES NOT FIT WITH THE SHIELD.

If you cannot afford BlueSMiRF module, then you can get a general adapter. This adapter is far cheaper than the BlueSMiRF module. It works perfectly with the shield and you can do all the experiments. BUY NOW

As stated before, the kit has been designed for Amarino and other Bluetooth based applications. In addition, you can use it for stacking HC-SR04 ultrasonic range finder and experiment with that. Even if you don’t know about Amarino, you can use it for LCD based Arduino experiments and other projects related to LDR, pulse width modulation (PWM), RGB LED, etc.

Display your SMS on LCD.

Send custom messages from phone and computer to Arduino via Bluetooth and display on LCD.

Experiment with phone events (for example, blink LED on phone calls).

Control RGB LED.

Display sensor graph on phone interface.

Display LM35 temperature sensor data on phone and simultaneously control the LED.

You cannot use it with Ethernet shield because the pins used for ethernet shield have been used for LCD. But, we are making another shield for ethernet shield and Amarino. You can buy this shield on minibread.com> http://www.minibread.com/23-bluetooth
